To all whom it may concern y p Be it known that I, CHARLES K. OLBERG,

a subject of theKing/,of Norwaygfand a resident of Philadelphia,l in the county of Philinvented certain ns7 and useful Improvements in Door-Casings, of which the folylowing is a specification..

lMy invention relates to' door-casings, and my'object is to provide an improved combined construction of door-buck with jainb and" trim, that is, a.r complete door- -asng,

"'Which may -be readily and inexpensively mea-ns whereby the trim .and the jamb ,are

Briefly, my invention comprises, chiefly:y a door-buck of improved design, which ina-y beassembled on the ground and positionl at thefdesired place, and in connection with Whiclrno wood ground or woodfacings need l be used, as is commonly the use, tov provide a surface to which the plaster may be fin-y ished, for a partition of brick andhollow.

Y Inorder that my invention may be more fully understood, attention is hereby dii'ected to the accompanyinglr drawings, 'forming part of this slwciiication and illustrat- Jin*k preferred embodiments of my invention. ky.n.fthedrawings, Figure `l represents a .frontelevatioh of adoor-casing installed.

Referring to the drawings, the door-buck is formed of vertical members 1 and 2 and cross-members 3, and 4, all preferably formed fot"channel-shaped steel sections secured together, and preferably adaptedv to be thus secured on the ground or, {loonbefore the erection of the buck, .inthe manner disclosed in the application ot' Olberg and wWalker, Serial No. 851,256, filed July 16, 191,4., entitled :Door bucks. Astheredescribed, the vertical'members are preferably provided with integral straps or pockets, by pressingout portions of the -inetal to leave strips such as 5 and G, referring to Fig. 1, the flanges at the ends of' the cross-members 3 and -l being eut away andthe bent ends,

as 7 and 8, of the web portions of the crossmeinbers, inseitedthrougl'i the pockets thus In other pockets on the vertical and10.are.iiiseited, these anchors having rightangular portions extending between courses of the wall or n'iasonry'as the saine is built, as is set forth in the said `application.` V

ln accordance with my invention. veach vertical nieniber, as 2," is formed withside .langesll and 12 having their endsbent 'out- .wardlv into an L Shape, as shown at 13 and 14 in Fig. Q. These angular extensions have several functions, one ot' which is to do away with the necessity ot' using wood grmluds, as is the coniinon practice.y toprovide surfaces to which the plaster muv be linisheil. the plaster being finished. in my construction, in line with the outer piane surfaces of extensions 13 and 1.4.' ".the4 L shaped extensions otpthe sidev flanges 11" and A12 o't the buck member are.lorniedjw ot' the flange. rThis rearward end-llang`e, havinga plane. surface` gives Ithe lino'to which rthe plaster is=li'iiislied.'bv resting a straight-edged board. t'or exanilvile, on this end yflange. Also the inner surfaces of the main or forward portions of the buck side shown. b v bending each ,flange at right?" angles outwardly from the body'thcreotll and ythen rearwardly. parallelto .the main body ksecuring means therefor.

v and wood members of flanges provide surfaces to which the brickwork, masonry or the like of the wall may be finished, and the outwardly extending legs of the L extensions provide abutnients for the forward edge of the plaster, defining the thickness of the plaster 15, 15, by their lengths, and furnishing a surface at right angles to the wall against which the forward edges of the plaster are formed. In addition to the above, an important function of the L shaped extensions consists in providing a space, below the surface of the plaster, between the extension of each side flange and the. face of the buck member, in which the securing devices for the trim may be located. By the provision of such a recess, the securing vdevices are concealed within the trim members, and the latter need not jut out so far from the wall as they would otherwise have to do, to accommodate the The top crossmember 3 of the buck has -similar L shaped ends 13' and 14' to its side flanges 11' and 12', as shown in Fig. 4, having similar functions to those of extensions 13 and 14 just de- ,scribedi By the arrangement described imresults aresecured, a considerable time and cost of erection is effected is eliminated from the construction.` The wallv oi partition of terra cotta, brick, or other desired material, Ais shown at 16.

For securingthe door trim 17 in osition I provide clips or hooks 18, which are secured, preferably by electric welding, to the flanges, as 11 and 12, of the vertical the buck, between the face of the buck member. and the L shaped extensions, as 13 and 14. These clips are adapted to enga e straps 19 which are secured, preferably liy electric welding, to the trim 17. Clips 18 are provided with upper ends 20 which are slightly flared outwardly, as is shown in Fig. 5, so that whenthe trim 17 is to be secured in position the trim must be raised untilall the straps 19 clear the tops 20 of hooks 18, after which the trim is forced downwardly, into position on both sides of the buck, with straps 19 resting within and retained by clips 18. It will be understood that there are as many clips 18 secured at spaced intervals to the flanges of the vertical members of the buck, and correspondingly spaced straps 19 secured to the. trim, as may deemed desirable, as is illustrated in Fig. 1. Because of the construction of the trim illustrated, and `-the arrangement of the clips and the straps, the fastening devices for the trim are concealed from Aview, the ends of straps 19 being secured to flanges on .the ends of the trim which extend inwardly, parallel to the outer surface of the trim.

At the top of the doorway, the clips or hooks 18 secured to the flanges 11' and l2 proved saving m the flanges 25 of the top member of the door-buck, preferably by welding, take a form such as is illustrated in Fig. 4, in which the upwardly extending and somewhat flared orbeveled arms 20 of the clips are engaged by the straps 19', secured to the trim 17', preferably by welding, when the trim has been lifted up and then orced down into position, with the stra s engaging the clips. The straps 19' pre erably .take the form substantially of an inverted U, as shown, each with one flat arni welded to the trim, and the other or free arm slightly flared or beveled to slide over the hook 20 when the trim is positioned. For further securing means for the top trim 17', upwardly extending members may be provided, secured, as by welding, to the 'flanges 13' and 14 of the top cross member of the buck, and having horizontalflanges at their upper ends, on which the top horizontal surfaces of the triml' rest when the trim is iressed downwardly to position. as describe it being understood that the trim has )reviously been assembled into :i complete rame. Securing means, such as screws 23, may, if desired, be theo passed through the horizontal engaging surfaces of trim 17 and members 22. y

The door-jamb 21 is secured to each vertical member of the buck.; refeiably by the means illustrated, in whiclli the clips 18 are shown as having side extensions 2 4, extending substantially parallel to the'flanges 11 and 12 of the vertical members of the buck, being bent outwardly from the surfaces of flanges 11 and 12, adpicent the welded joints between the clips and flanges 11 and 12',y

sufficiently to permit end flanges of the jamb to be inserted between Yclip portions 24 and flanges 11 and 12 of the buck. lVhen flanges 25 of the jainb have been positioned within retainer clip portions 24 of clips 18, nails 26 or other suitable retaining means may be passed through alined openings in flanges 24, 25, and 11 on the one side, and 2l, and 12 on the other side, and into the partition 16, to secure the jamh. At the top of the door, the same construction is used, hooks 18 having downwardly extending portions 24 between which and flanges 11' and 12 of the to member of the buck may be placed, and securedin place by suitable means, such as nails 26. In the case of the verticalv 'amb members, straps 19 may be so form as to have surfaces of t e jamb member 21 4 in linewith the heads of nails 26, when the trim members have` been positioned, so that even if nails 26 workloose, they cannot come all the way out.

gAs will readily be seen from the above, in the assemblage -of the door-casing, the

buck is assembled, with clips 18 and 18 secured to the same,erected, and anchored to the wall as the latter is built, plaster 15 and straps secured to the trim members, adapted to slidably engage said clips, substantially as set forth.

5. In a door-casing, the combination of a buck member, having a side flange, a janib member secured against the front of the buck member, and having a side flange ositioned against the side flange of the )uck member, a trim member having inner flanges arranged to lie against the side flanges of the jamb member and the wall respectively, horizontal straps secured tosaid flanges, upwardly extendin clips secured to said buck member side fliinge, having outwardlyflared upper ends, said straps being positioned to slidably engage over said clips with a wedging action when said trim member is slid into engaging position, to hold said trim member tightly in position, substantially as set forth. L
